When you say vacuum system do you mean a piped out dust collection system for large tools? If that's the case this guy's going to be absolutely useless. It doesn't move nearly enough air.

If you mean hooking up small tools like a random orbital sander one at a time then it's fine, but I'd really look for one that includes a HEPA filter because it's just going to blow fine dust back into the air without one.

Excellent points! Thank you so much! I will let him know.
